END-GATE FOR WAGON S.

Specification of Letters Patent.

Patented June 2, 1914.

vApplication filed August 5, 1912. Serial No. 713,233.

To all whom t may concern:

Be it known that I, JOSEPH H. Konmar., a citizen of the United States, residing 1n the city of Wayland, county of Henry, and

State of Iowa, have invented certain new and useful Improvements inEnd-Gates for Wagons, of which the following is a speci- Iication.

This invention relates to improvements 1n end gates for wagons and has among its salient objects .to provide a construction which is self locked against endwise or lateral displacement, and at the same time so interlocks with the side boards as to prevent spreading of the latter; to provide a construction of the character referred t0 which dispenses with ,any tie rods, locking ybolts or other extraneous fastening devices; to provide a construction in which the end gate is equipped with a plurality of anti friction rollers whereby the former may be readily slippedl into or out of engagement with the side boards; to provide a construction in which the end gates form a tight fit with the side boards so as to prevent leakage of grain or other similar'material, in which the end gates and side boards effectively brace each other so as to form a rigid structure a'nd in which the end gate may nevertheless be removed or inserted in place without binding; to providea construction in which the end gates may be made, if desired in a plurality of sections, and to provide simple and novel means for locking the sections together and for locking the end gates as a whole against vertical displacement; to rovide a cpnstruction in which the interlocyingl parts are in effect concealed, thus not only preventing injury to such parts, but giving a workman-like appearance to the end gates as a whole; and in general to provide simple and economical construction of thev character referred to.

The invention consists in thev matters hereinafter described and more particularly l pointed out in the appended claims.

In the drawings Figure 1 is a rear end elevation of a wagon equipped with my mproved end' gate; Fig. 2 is a fragmentary top plan view of the construction shown in Fig. 1; 3 is a fragmentary horizontal sectional view taken on lines 3-3 of Fig. 1

and looking in the direction of the arrows; Fig. 4 is a similar view taken on lines 4--4 of Fig. 1 and looking in the direction of the arrows; Fig. 5 is a fragmentary vertical sectional view taken through the central part of the gate.

Referring to the drawings 1 designates the bottom or bed of a wagon body, 2 and 3 ythe side boards and 1.the end gate. In the present instance the end gate is shown as made in two sections 5 and 6 respectively, the sections being detachably locked t0- gether by means of a spring clip 7 secured to the upper section 6 as shown at 8, and provided with an inturned lip or flange 9 which engages a suitable recess 10 in the lower section It is to be understood of course, that the number of sections in which the end gate may be made, may be varied as desired, or may be made' all` in one piece. To receive the end gate there is secured to each of the side boards a vertically extending channel member 11. The base member 12 of each of these channels is provided with a web-like extension 13, 14, by which it may be'rnore readily secured to the adjacent side board. The inner vertically extendingiiange 15 of the respective channel members 11, 1n eli'ect serves as a track rail for the anti-l friction rollers of the end gates, hereinafter described.

Describing 4now the coperating interlock ing mem-bers carried by the end gate, each sectionjs provided at its vertical edge with a channel member 20, which is securedto the outer face of the end gate by means of a web or flange extension 21 as shown more clearly in Figs. 3 and 4. Within each 5f these channel members 20 is rotatably journaled a plurality of anti-friction rollers 22, soar-ranged that when the end gate is in position the wheels will normally ride on the track rail 15 of the eoperating channel member l1. To prevent the end gate from outward displacement, on th'e inside of each end gate section is fixedly secured a coniining liange 23, the outer end of which is preferably provided with an olf set extenbe easily withdrawn without binding for.

the purpose of unloading. To prevent vertical displacement of the end gate, as well as to avoid rattling I provide a bottom secsion 24 which overlaps the adjacent side of' tion 5 with a spring latch bar 25, the ends of which are provided with offset portions 26 terminating in right angle extensions 27. The ends 27 of the latch bar pass through suitable apertures in the sides of the channel members 20 and are adapted to have locking engagement with the similar apertures in the adjacent channel member 11. The off set portions 26 in effect serve as hand holds to which the ends 27 of the latch bar may be readily withdrawn from engagement with the channel member l1 in order to remove the end gate. Preferably the intermediate portions of the latch bar are coniined in suitable eyes 28 as shown more clearly in Figs. l and 2.

The manner in which the end gate is removed or inserted in place is obvious from the foregoing' description and need not be described further in detail. It is understood of course, that in inserting the end gate in place or removing it, the latches should be withdrawn from engagement with the channel members of .the side boards. Preferably the channel members and locking flanges 23 are made of sheet metal so as to avoid bindin by warping. It should be noted not only t at the interlocking channel members may be easily and cheaply constructed but that the end gate and side boards are effectively locked without the aid of any tie rods and without the necessity of using any wrench, or other tools as is necessary in constructions now in general use. I am aware that heretofore various forms of end gates have `been patented, but none of them, as far as I know, have embodied the simplicity and effectiveness found in the 'present construction. It should also be noted that when the end gate is in position it is flush with the adjacent edge of the side boards and that the parts so interlock as to form in eii'ect a grain tight seal at the rear end of the wagon.

The invention is not limited to the details of construction shown except as set forth in the appended/claims.

I claim as my invention:

l. The combination with a wagon body the side boards of which vare provided at the rear end with vertical channel members, the open sides of whieh'face rearwardly, of an end gate provided at each end with a vertical channel member the open'sides of which face the ends of said gate, `a ange extension secured to the inner face of said gate at each end, and anti-friction rollers journaled between the sides of channel members of the gate and adapted to travel in Contact with the inner or free flanges of the channel members of the side boards.

2. The combination with a wa on body the side boards of which are provi ed at the rear end with vertical channel members, the open sides of which face rearwardly, of an end gate provided atv each end witha vertical channel memberthe open sides of which face the ends of said gate, a flange extension secured to the inner face of said gate at each, end, anti-friction rollers journaled between the sides of channel members of the gate and adapted to travel in contact with the inner or free flanges of the channel members of the side boards, registering openings in the channel members of the side boards and gate ends, and a spring latch bar provided at`its ends with angular extensions adapted to iit the openings of said channel members.
